Concave c2d?

Baka^Ni · 5 Feb 2007 at 03:17

After giving my sythe ninja a good saw so that it would fit in my evga 680i it fits nice and tightly. However my temps are ridiculous, 60c idle and it goes up easily to 70+ with TAT :S I so wanted to overclock the e66 but with stock temps like that it looks like a pipe dream.

So I've ripped off the hsf, assuming it wasn't attached correctly and bizarely it seems only the edges of my ninja are making contact with the cpu? There is a thin line of thermal paste around the edge but none in the middle.

Are c2ds concave or something? why would it make contact around the edge but not in the middle. Defective? Stupid hsf? Ideas?

Christ, WHAT! File down my cpu? That's insane...

Surely there must be a less ridiculous way to solve this then rubbing bits off my chip. For example, using tons of arctic silver?

What on earth? I had zero problems fitting my Ninja into the BFG 680i I had.

The evga i680 has 4 black chip thingies on the top of the heatsink mount, as the ninja sythes base is circular and not square, you cannot clamp the heatsink down without chopping the mounting bracket or damaging the R50? chips.

Also as a slight rant, whoever thought of putting a really dodgy cap next to one of the mounting holes was a real prat, every time I fiddle with the hsf I'm scared it's gonna snap off.

another vote for lapping the cpu, there really isn't a more logical way to get those temps down! applying too much AS5 mite not always have the desired effect but lapping will definately get you better temp drops!

Filling the space with as5 seems like a crap solution

at least compared to lapping, right, I'm gonna lap it, this stupid idea really can't go wrong

.

Thanks to whoever did that lapping guide, will try it when I can find some of those grade sandpaper.

Slight EDIT: I have a tube of AS3 here, from my old P4 build, is it really that much different from AS5? I'm reluctant to order just one tube of AS5 when I already have loads of AS3.

Oooohhhh, I get you. You must be using the Ninja Revision B.

I'm using Revision A, which is fastened on by two "scaffold like" mounts that clips on the Ninja fasten to. The mounts tower over the capacitors on every motherboard I've tried so far, so I'm not sure why Scythe decided to alter the design so drastically.

If I were you, I'd try to get hold of a Revision A, truly universal.

Yes it's the Rev B, Doh. Not a problem now anyway, me and my good friend mr saw solved the problem in 30mins

Done, lapped, 38c idle, 22c off my old temp

Amazing =)

I do have a few pics, they're on the other pc at the moment, too lazy to copy across and upload

The chip isn't nice and shiny as I've seen others brag about

but it's flat as a pancake and has knocked down my temps significantly. Having never really lapped anything before, I wasn't sure how much copper I could rub off before I hit something vital.

I have another really weird problem, I'll post another thread as to not derail this one.
